You can do this by using the battery and then get a 12v usb Socket like the ones you can get for cars etc, we did this of another usb powered device outside, and also connected a solar battery charger to the battery, so far haven’t had to charge the battery, but now winternis her and less sun we will see

Thanks a lot for the suggestion. I don’t have a voltmeter but when I opened the motion detector, the little board labeled it had 12VDC coming in. The battery backup in the panel pushes out 12V. 7 amps according to the side label it has on it. I bought a converter to use at the end and see if it works. If it does, I have the added benefit of having the cameras on battery as well as my wifi (separate backup already used). Attached is a picture of the board.

Anyone have a solution for using house doorbell AC wiring (the two wires that normally power the doorbell ringer) to power USB? I want to install my soon to be 5th (I’m hooked) WyzeCam at my front door. I have no outdoor power at my front door, and I don’t want to have to drill and pull power through my exterior wall insulation. Since I installed a wireless doorbell years ago, I have the doorbell AC power wires sitting unused right where I need them; however, I’ve been unable to find something t…

A dashcam powering kit connected to a 12VDC battery will work fine.

The V2 camera draws about 300mA @ 5VDC in day time. Somewhat more in Night mode when the IR illuminators light up.
If you’re powering a dash cam power kit (or other DC-to-DC converter) from a 12VDC battery, the current draw @ 12VDC will be about 140mA (daytime). You can do the math and figure out how long a big 12VDC battery would last, depending on hours of daylight, whether you have night mode enabled, ambient temperature, etc.

There are a lot of posts here by people looking at the possibility of using solar cells to keep a battery charged up. The cam consumes a couple of watts, so you’ll need a solar array of perhaps 8W or more to keep the cam running 7x24 (depending on your latitude, etc).

Or forget the battery, and run an exterior-rated cable to get 12VDC out to the camera location, then a dashcam kit to convert to 5VDC. RG-6/U coax is one option. I repurposed a CATV drop to get power out to the utility pole in front of my house.

As far as I can see, you can just follow the manuals of your wyze cam, which is good for the durability of the cam itself.
When I use the WingHome trail camera, I feel boring about using the 12AA batteries, so I use the solar panel finally, and it works well. What’s important, I do follow the instructions on the product manuals.
